[0020] like Figure 1 and Figure 2 As shown, first, the spring ring 61 is fixed by the upper rotating disk 11, and then the upper rotating disk 11 is rotated. After the two clamping arms 62 are separated by the torsion force of the upper rotating disk 11, the two clamping pieces 5 are placed in the installation space between the clamping arms 62 and the spring ring 61, and then the torsion force of the torsion bar 3 on the clamping arms 62 is released by the locking mechanism 4. After the elastic force of the clamping arms 62 is restored, the two clamping pieces 5 are clamped on the spring ring 61, thereby completing the installation of the spring clip. The present application uses the upper rotating disk 11 to fix the spring ring 61 and separate the clamping arms 62, and after the torsion force of the upper rotating disk 11 on the clamping arms 62 is released by the locking mechanism 4, the elastic force of the spring ring 61 is used to complete the assembly, thereby replacing the method of workers using their fingers to separate the clamping arms 62, thus avoiding excessive strain on the workers' fingers and improving production efficiency. In a feasible embodiment, the locking mechanism 4 includes a hinged rod 41 and a push pin 42, the rod body of the hinged rod 41 is rotatably connected to the upper table panel 1, one end of the hinged rod 41 is hinged to the push pin 42, and the other end is provided with a driving inclined surface 416, the upper table panel 1 is provided with a first plug hole 13, and the upper rotating disk 11 is provided with a second plug hole 111 corresponding to the first plug hole 13, the push pin 42 is used to be inserted into the first plug hole 13 and the second plug hole 111 from bottom to top in sequence to limit the rotation of the upper rotating disk 11 relative to the upper table panel 1, and the driving inclined surface 416 is used to abut against the clip 5.

[0021] Further, the hinge rod 41 includes a first cross bar 413, a second cross bar 414 and an oblique rod 415, the first cross bar 413 and the second cross bar 414 are respectively arranged at two ends of the oblique rod 415, the oblique rod 415 is tilted, the first cross bar 413 is located below the second cross bar 414, the driving inclined surface 416 is arranged on the first cross bar 413, the ejector pin 42 is hinged to the second cross bar 414, the connection between the second cross bar 414 and the oblique rod 415 is rotatably connected to the upper table panel 1, the second cross bar 414 is used to rotate upward around the connection to drive the ejector pin 42 to be inserted into the first plug hole 13 and the second plug hole 111 from bottom to top in sequence, the first cross bar 413 and the oblique rod 415 are used to rotate upward around the connection to drive the ejector pin 42 to disengage from the second plug hole 111 from top to bottom. In this embodiment, in order to allow the ejector pin 42 to be smoothly inserted into the first plug hole 13 and the second plug hole 111, the gravity of the first cross bar 413 and the inclined rod 415 is greater than the gravity of the second cross bar 414 and the ejector pin 42, so that the second cross bar 414 rotates upward, driving the ejector pin 42 to enter the first plug hole 13 and the second plug hole 111. When the driving inclined surface 416 is subjected to the pressure applied vertically to the driving inclined surface 416 by the clip 5, the pressure is decomposed into a component force in the vertical direction. At this time, the gravity of the first cross bar 413 and the inclined rod 415 will be less than the gravity of the second cross bar 414 and the ejector pin 42 after offsetting the component force in the vertical direction. Under the gravity of the second cross bar 414 and the ejector pin 42, the ejector pin 42 is separated from the second plug hole 111 from top to bottom, and then the upper rotating disk 11 and the upper table panel 1 can rotate relative to each other.

[0022] In a feasible embodiment, a second tension spring 14 is provided in the first plug hole 13, and the second tension spring 14 is used to pull the ejector pin 42 to be inserted into the first plug hole 13 and the second plug hole 111 from bottom to top. In this embodiment, after the tension spring is superimposed on the gravity of the first cross bar 413 and the inclined bar 415, it is further ensured that the ejector pin 42 can enter the first plug hole 13 and the second plug hole 111.

[0023] In a feasible embodiment, the upper rotating disk 11 includes a torsion bar 3 and a chuck 115, a cover body 12 is provided on the upper table panel 1, the chuck 115 is located in the cover body 12, and is rotatably connected to the upper table panel 1, one end of the torsion bar 3 passes through the cover body 12, the chuck 115 and the upper table panel 1 in sequence and extends to the bottom of the upper table panel 1, and the other end passes through the cover body 12 and extends to the top of the cover body 12, and a clamping block 31 is convexly provided on the rod body of the torsion bar 3, the The clamping block 31 is located in the cover body 12. The clamping block 31 is used to move up and down along the vertical direction to clamp on the chuck 115 or separate from the chuck 115. A compression spring 32 is provided between the clamping block 31 and the cover body 12. The compression spring 32 is used to drive the clamping block 31 to clamp on the chuck 115 along the vertical direction, so that the torsion bar 3 drives the chuck 115 to rotate. The upper plug pin 33 and the upper clamp pin 34 are provided on the end surface of the torsion bar 3 close to the upper table panel 1. In this embodiment, in combination with the above-mentioned multiple embodiments, the assembly method is specifically as follows: Place the spring clip 6, pull up the torsion bar 3 in the vertical direction, so that there is a space between the upper pin 33 and the lower pin 21 for the spring ring 61 to enter, at this time the compression spring 32 is compressed between the clamping block 31 and the cover body 12, the spring ring 61 is sleeved on the lower pin 21, the clamping arm 62 close to the lower table panel 2 is abutted against the lower clamping pin 22, and the torsion bar 3 is released. The clamping block 31 is clamped on the upper rotating disk 11 in the vertical direction under the elastic force of the compression spring 32, and at the same time, the upper pin 33 is inserted into the spring ring 61, and the clamping arm 62 close to the upper table panel 1 abuts against the upper clamping pin 34, and the upper pin 33 cooperates with the lower pin 21 to fix the spring ring 61; The upper rotating disk 11 is fixed, and the torsion bar 3 is screwed, so that the upper clamping pin 34 moves the clamping arm 62 close to the upper table panel 1, thereby gradually increasing the angle between the two clamping arms 62, until a space for a clamping piece 5 to enter appears between one of the clamping arms 62 and the spring ring 61, and the elastic force of the spring ring 61 is gradually increased. At the same time, the first plug hole 13 is aligned with the second plug hole 111, and the ejector pin 42 is inserted into the first plug hole 13 and the second plug hole 111 from bottom to top in sequence to limit the upper rotating disk 11 from rotating relative to the upper table panel 1; Place the clips 5, insert one of the clips 5 into the space between one of the clip arms 62 and the spring ring 61 along the horizontal direction, and insert another of the clips 5 into the space between another of the clip arms 62 and the spring ring 61 along the horizontal direction, so that the spring ring 61 is located between the two clips 5; Release the upper rotating disk 11, and push the two clips 5 in the horizontal direction at the same time until they abut against the driving inclined surface 416 to apply pressure to the driving inclined surface 416. The driving inclined surface 416 decomposes the pressure applied by the clip 5 into a vertical upward component to drive the hinge rod 41 to rotate around the connection, thereby driving the ejector pin 42 to disengage from the second plug hole 111 from top to bottom. Under the elastic force of the spring ring 61, the clamp arm 62 close to the upper table panel 1 moves the upper clamping pin 34 to drive the torsion bar 3 to return to its original position, and at the same time moves one of the clips 5 close to the spring ring 61, and the upper rotating disk 11 returns to its original position driven by the torsion bar 3; Take the clip and pull up the torsion bar 3 in the vertical direction, so that there is a space between the upper pin 33 and the lower pin 21 for the spring clip 6 and the clip 5 to be taken out, and then take out the spring clip 6 and the clip 5, so that the spring ring 61 is disengaged from the lower pin 21, and the clamping arm 62 close to the lower table panel 2 is separated from the lower pin 21. Under the elastic force of the spring ring 61, the two clamping arms 62 clamp the clip 5, and the spring clip is assembled.

[0024] In a feasible embodiment, the clamping block 31 includes a central portion 311 and a plurality of protrusions 312, and the plurality of protrusions 312 are evenly spaced around the central axis of the torsion bar 3 on the peripheral wall surface of the central portion 311, and the chuck 115 is provided with a central hole 112 and a plurality of recessed grooves 113, and the plurality of recessed grooves 113 are all connected to the central hole 112, and the central hole 112 can be inserted from top to bottom into the torsion bar 3 and the clamping block 31, and the recessed grooves 113 can be inserted from top to bottom into the protrusions 312 to clamp the clamping block 31 onto the chuck 115.

[0025] In a feasible embodiment, a stop plate 114 is provided at the bottom of the recessed groove 113, and the stop plate 114 is used to limit the position of the protrusion 312 in the recessed groove 113. In this embodiment, the stop plate 114 prevents the torsion bar 3 from moving downward, thereby preventing the clamping block 31 from detaching from the upper rotating disk 11 under the action of gravity.

[0026] In a feasible embodiment, the lower table panel 2 is rotatably connected to a side of the upper table panel 1 with a lower rotating disk 23, and the lower rotating disk 23 is provided with a plurality of mounting grooves 231, and the plurality of mounting grooves 231 are evenly spaced around the circumference of the lower rotating disk 23, and each of the mounting grooves 231 is provided with the lower plug pin 21 and the lower clamping pin 22. In this embodiment, since the lower rotating disk 23 can rotate and the lower rotating disk 23 is provided with a plurality of mounting grooves 231, the spring clip 6 can be pre-installed on the mounting groove 231 closest to the worker. Then, the lower rotating disk 23 rotates so that the mounting groove 231 rotates toward the torsion bar 3. The plurality of mounting grooves 231 with the spring clips 6 installed sequentially enter the lower part of the torsion bar 3 and are assembled with the clip. The number of mounting grooves 231 can be set according to actual conditions, and is generally set to be mounting grooves 231. Due to the setting of the lower rotating disk 23, the spring clip can be installed in a collaborative operation mode between two workers. A worker 1 is arranged on the side of the lower rotating disk 23 away from the torsion bar 3, and another worker 2 is arranged on the other side. The worker 1 places the spring clip 6 in the installation groove 231, and at the same time, the worker 2 takes out the assembled spring clip under the torsion bar 3. Then the lower rotating disk 23 is rotated to rotate the installation groove 231 with the spring clip 6 to the bottom of the torsion bar 3, the worker 2 twists the torsion bar 3 and places the clip 5, and the worker 1 places the spring clip 6 in the installation groove 231 where the spring clip 6 has not been placed. Such a cyclic operation greatly improves the efficiency of assembling the spring clip.

[0027] In a feasible embodiment, the lower table panel 2 is provided with a third plug hole 24, the lower rotating disk 23 is provided with a fourth plug hole 232 corresponding to the third plug hole 24, the third plug hole 24 is provided with a first tension spring 25, the first tension spring 25 is connected with a limit pin 26, the limit pin 26 is used to be inserted into the third plug hole 24 and the fourth plug hole 232 from bottom to top under the elastic force of the first tension spring 25, so as to limit the rotation of the lower rotating disk 23 relative to the lower table panel 2. Since the lower rotating disk 23 is in a rotating state, it is easy to have the problem of misalignment with the torsion bar 3. Therefore, the limit pin 26 is inserted into the third plug hole 24 and the fourth plug hole 232 to position the lower rotating disk 23, so as to ensure that the spring clip 6 and the torsion bar 3 are accurately positioned. Further, the third plug hole 24 is provided with a plurality of limit pins 26, and the end of the limit pin 26 is set to a semi-spherical shape. When the stop pin 26 enters the third plug hole 24 and the fourth plug hole 232 at the same time, only the semi-spherical end enters the fourth plug hole 232. When the lower rotating disk 23 is rotated, since the surface where the semi-spherical end contacts the lower rotating disk 23 is an arc surface, the lower rotating disk 23 forms an extrusion on the arc surface, driving the stop pin 26 to move downward, the stop pin 26 leaves the fourth plug hole 232 and abuts against the lower surface of the lower rotating disk 23, and at the same time stretches the first tension spring 25. When the lower rotating disk 23 rotates to the point where the third plug hole 24 corresponds to the fourth plug hole 232, under the elastic force of the first tension spring 25, the stop pin 26 enters the third plug hole 24 and the fourth plug hole 232 to complete the positioning. Since the semi-spherical end can form a small resistance to the rotation of the lower rotating disk 23, and does not affect the rotation of the lower rotating disk 23, the positioning of the lower rotating disk 23 is completed by the small resistance of the semi-spherical end.

[0028] In a feasible embodiment, a handle 35 is provided at one end of the torsion bar 3 extending outside the cover body 12, and the handle 35 is used to drive the torsion bar 3 to move or rotate. In this embodiment, the setting of the handle 35 can provide a support point for the force when the torsion bar 3 is moved upward, and can also increase the torque when the torsion bar 3 is twisted.

[0029] The present invention further provides an assembly method, which is applied to the assembly device of the spring clip described in any one of the above items, and comprises the following steps: Place the spring clip 6, put the spring ring 61 on the lower pin 21, make the clamp arm 62 close to the lower panel 2 abut against the lower clamp pin 22, and at the same time, the upper pin 33 is inserted into the spring ring 61, and the clamp arm 62 close to the upper panel 1 abuts against the upper clamp pin 34, and the upper pin 33 cooperates with the lower pin 21 to fix the spring ring 61; The upper rotating disk 11 is fixed and rotated, so that the upper clamping pin 34 moves the clamping arm 62 close to the upper table panel 1, thereby gradually increasing the angle between the two clamping arms 62, until an installation space for a clamping piece 5 to enter appears between one clamping arm 62 and the spring ring 61, and the elastic force of the spring ring 61 also gradually increases, and the upper rotating disk 11 of the locking mechanism 4 rotates; Place the clip 5, insert one of the clips 5 into the installation space between one of the clip arms 62 and the spring ring 61 along the horizontal direction, and insert another of the clips 5 into the installation space between another of the clip arms 62 and the spring ring 61 along the horizontal direction, at this time, the spring ring 61 is located between the two clips 5; Release the upper rotating disk 11, push the two clips 5 in the horizontal direction at the same time until the clips 5 contact the locking mechanism 4, and drive the locking mechanism 4 to unlock, thereby driving the other end to release the restriction on the upper rotating disk 11 and the upper table panel 1. Under the elastic force of the spring coil 61, the clamping arm 62 close to the upper table panel 1 pushes the upper clamping pin 34 to drive the upper rotating disk 11 to return, and the two clamping arms 62 drive the two clips 5 to move closer to complete the clamping.

[0030] The above-mentioned assembly method uses the upper rotating disk 11 to fix the spring ring 61 and separate the clamping arm 62, and uses the elastic force of the spring ring 61 to complete the assembly after releasing the torsion force of the torsion bar 3 on the clamping arm 62 through the locking mechanism 4, thereby replacing the method of workers using their fingers to separate the clamping arm 62, avoiding excessive strain on the workers' fingers and improving production efficiency.
